DESCRIPTION
The TPS2560A and TPS2561A are dual-channel
power-distribution switches intended for applications
where precision current limiting is required or heavy
capacitive loads and short circuits are encountered.
These devices offer a programmable current-limit
threshold between 250 mA and 2.8 A (typ) per
channel via an external resistor. The power-switch
rise and fall times are controlled to minimize current
surges during turn on/off.
Each channel of the TPS2560A/61A devices limits
the output current to a safe level by switching into a
constant-current mode when the output load exceeds
the current-limit threshold. The FAULTx logic output
for each channel independently asserts low during
overcurrent and over temperature conditions.
